MEANS FOR RAISING PILE OR NAP ON FABRICS.

SPECIFICATION forming part of Letters Patent No. 658,539, dated September 25, 1900.

Application led August 23, 1899. Serial No. 728,172. (No model.)

To @ZZ whom, t may concern.:

Be it known that we, WILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIC E; KIP, residing at Montclair, Essexcounty, New Jersey, citizens of the United States, have invented lcertain new and useful Improvements in Means for Raising Pile er Nap on Fabrics, of which the following is a specication.

This invention has for its object to raise the pile or nap on a woven fabric with theaid of static or frictional electricity.

At a certain stage in the manufacture of fabrics, and particularly of cut-pile fabrics, the pile or nap lies down flat and must be made to stand erectandpresent a uniform appearance, such as' may be seen in finished and the object of the machine or device embodying the present invelntion to Veifectfwthis raising of the nap or p1 e. l

A`In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is an end elevation of theapparatus, and Figs. 3 and 4 are fragmentary detail views, on a larger scale, illustrating the construction and operation of the apparatus.

a, represents any suitable base for the apparatus, 'which may be connected with the earth or ground, and b represents, as a Whole,

Y a suitable frame mounted on and insulated from said base. Conveniently the frame b may be made of two arched members, of metal, connected and rendered rigid by suitable tie rods or bars. The two arched members provide four feet, upon which the frame is supported, and for insulating the frame these feet may be set in glass receptacles c, set in the base a and partly filled with oil d, as indicated in Fig. 1,where these glass insulatingreceptacles are seen in section.

Mounted on the base a, or on the earth is a V-edged saddle-bar e, of metal or partly of metal, over which` passes the fabric f to be treated. By the breaking of the fabric over the bar e at an angle the pile or nap thereon is somewhat opened.

Directly over and the bar e is mounted which will be,

n i. 4g

adjacent to the edge of in the frame b a bar g, by preference, mounted so s to be capable of some vertical adjustmentthat is to say, the ends of this bar g occupy keeper-slots h, Fig. 4, in the end members of the frame b and are pivotally coupled to yokes 1I, which embrace each an eccentric j, fixed on a shaft k, rotatively mounted on the frame b and provided with some means of turning it-as a crank l, for example.

The bar g has at its lower side, directly over and parallel with the V edge of the sad-- die-bar e, a thin strip or edge piece of metal m, or, as an equivalent thereof, a row of metal teeth to form a comb, as indicated in Fig. 3. This strip or piece fm, in whatever shape it is made, forms the positive pole or terminal of a static electrical machine n, (indicated somewhat diagrammatically in Fig. 2,) With'which machine it will be properly connected, and the bar e may be connected with the earth.

The fabric f will be moved or drawn at a proper speedbver the bar e by any suitable mechanism, the pile or nap being uppermost, and a static electrical discharge flowing from the terminal m to the bar e will cause the bers of the pile or nap to separate and stand erect.

Any means may be employed for drawing the strip of fabric f over the saddle-bar e. That herein shown consists of a plain rollero and a toothed roller p, ing put on the fabric at the other side by rollers q and r. All that is needed for feeding the cloth is means for moving it along at the proper speed and means for puttinga suitable tension on it as it is drawn over the' bar e.

The device for adjusting the terminals m up or down, and in consequence farther from or nearer to the fabric where it passes over the proper tension bethe bar e, may have, of course, any suitable" construction. That shown will serve the purpose.

While we contemplate the employment of4 a known form of machine for producing what is called frictionalflelectricity, it must be understood that our'invention is not limited in this respect. Any machine or generator capable of producing electricity of high tension corresponding to what is producedby the friction-machines will serve.

Being the first, as we believe, in this field IOO of invention, we claim the same broadly and would consider as coming within the scope of our invention any device or means for raising the pile or nap on a fabric wherein electricity is employed for effecting the result.

Having thus described our invention, we claiml. Means for raising the nap or pile on fabrics, comprising a bar over which the fabric may be drawn, a'generator of electricity of high tension, and a terminal of such generator arranged parallel to, but out of contact with said bar, and adjacent to that edge of the latter over which the fabric is drawn.

Means for raising the nap or pile on fabrics, comprising a saddle` bar over which the fabric is drawn with the pile outward, mechanism for moving the fabric over said bar while under tension, an elongated terminal adjacent to the pile on the fabric along the 'line where the latter passes over the saddlebar, and a generator of electricity of high tension, said terminal being connected with one pole of the ,said generator.

3. Means for raising the nap or pile on fabrics, comprising a V-edged saddle-bar over which the fabric is drawn at au angle with the pile outward, mechanism for moving the fabric over said bar while under tension, a generator of electricity of high tension, and a bar-like terminal of said generator situated adjacent to and parallel with the edge of said saddle-bar.

4. In means for raising the nap or pile on fabrics, the combination with the saddle-bar e, and mechanism for drawing the fabric over the same, of a generator of electricity of high tension, an adjustable terminal of said generator, situated parallel with and adjacent to the bar c, and means for adjusting said terminal with respect to the bar e.
